CLAMP FOR SLIDING DOORS.

SPECIFICATION forming part of Letters Patent No. 439,886, dated November4, 1890. Application filed January 2, 1890- Serial No. 335 ,566- (Nomodel.)

To all whom it may concern.-

Be it known that I, EDWARD Y. MOORE, of Milwaukee, in the county ofMilwaukee, and in the State of Wisconsin, have invented certain new anduseful Improvements in Clamps for Sliding Doors; and I do hereby declarethat the following is a full, clear, and exact description thereof.

My invention relates to clamps for sliding doors; and it consists incertain peculiarities of construction and combination of parts to behereinafter described with reference to the accompanying drawings, andsubsequently claimed.

In the drawings, Figure 1 represents a side elevation of a portion of afreight-car provided with a sliding door and a clamp constructedaccording to my invention; Fig. 2, a vertical transverse section of thedoor and clamp, and Fig. 3 a horizontal section of said clamp.

Referring by letter to the drawings, A represents a portion of afreight-car; B, a track secured to a side of the car, and O a doorsuspended from the track by means of traveling hangers D of any suitableconstruction.

Secured to the car is a bracket E, having a horizontal portion 1),approximately equal in width to the thickness of the door 0, and risingfrom this horizontal portion of the bracket is a vertically-disposed,but preferably inclined, portion (3, the side edges of which engagegrooves d in a Wedge F, the top of the latter being extended outwardfrom the inclined portion of said bracket far enough to form a grip e,as illustrated in Fig. 2.

In order to prevent withdrawal of the wedge F,I prefer to provide theinclined portion 0 of the bracket E with a longitudinal recess f forengagement with a pin or screw g, that has its bearing h on said wedge.

In practice the wedge F by its own gravity clamps the door O tightagainst the car, and thereby prevents said door from sliding in eitherdirection. In order to permit travel of the door, it is necessary forthe operator to raise the wedge by grasping the outwardlyextendedportion 9 of its top, and the moment said wedge is released it fallsback on the inclined portion 0 of the bracket E to clamp said door inits adjusted position.

By-the above description it will be seen that the door may be heldclosed, open, or

partly open, and that I do away with the necessity of a guard-rail toprevent said door from swinging out from the car.

While I have described the clamp in connection with a sliding car-door,it is obvious that said clamp may be employed in connection with anysliding door.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A sliding-door clamp that comprises a bracket having ahorizontally-disposed portion approximately equal in width to thethickness of the door, a vertically-disposed portion rising therefrom,and a wedge loosely arranged on the vertically-disposed portion,substantially as set forth.

2. A sliding-door clamp that comprises a bracket having ahorizontally-disposed portion approximately equal in width to thethickness of the door, an inclined portion rising therefrom, and agravity-wedge loosely arranged on the inclined portion, substantially asset forth.

3. A sliding door clamp that comprises a bracket having avertically-disposed portion and a gravity-wedge provided with groovesengaging the side edges of said verticallydisposed portion of thebracket, substantially as set forth.

4. A sliding-door clamp that comprises a bracket having avertically-disposed portion provided with a longitudinal recess, agravity-wedge loosely arranged on said verticallydiposed portion of thebracket, and a stop extended from the wedge into said recess,substantially as set forth.

5. A slidingdoor clamp that comprises a bracket having ahorizontally-disposed portion approximately equal in Width to thethickness of the door, a vertically-disposed portion rising therefrom, awedge loosely arranged ou the vertically-disposed portion, and the topof the wedge extended outward to form a grip, substantially as setforth.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of VViscousin, in thepresence of two witnesses.
